Got the head back last week. It better go as good as it looks.

It's had 13hrs worth of porting done, valve seating, head plained, new heavy duty valve springs and cam followers.

The cams are new 280° to match the intakes.

We just have to setup the cams in the head and it's ready to go on for the test fitting of the itb's.

Hopefully the fabrication of these will be done in the next week or two.

The ports have had a lot of work done on them to change the size and entry angle of the port to the valves, should make a good difference there.

This week I have to sus out an ECU to run the thing.

oh man..

oh baby..

that so farkin hot!

Could I ask a rough price for the project?

Could you write up how much better the responce is? how much and where in the rev range the improvements where?

Dunno Rach, just kinda doing it on the side. At the moment I'm waiting for some alloy tube to turn up for the runners, then it's a matter of getting it all tigged up.

Think I'm going to run a Link G3 with a tps and map.

You think thats hot, wait till I've got the trumpets on it, mmmmm. :D

Cost so far... NZ$300 for itb's and NZ$2,900 for the head and cam work (mates rates!)

My mate is doing the CNC machining, so I'll see if I can buy him out with beer. :D

Hey mate,

Nice work. Looking good.

I recently built an RB30DE using 25DE head from an R32 with a modified RB26 6 throttle inlet to fit. Throttle response is unbelievable! I find myself rolling off the power just so I can nail it again. Havent go mine fully tuned yet... Only tuned to 4000rpm. It currently makes 86kW at wheels at 3000rpm (10BTDC and a little rich) so I cant wait to unleash it!

Yours should be somthing along these lines too!! What compression did you end up with?

Again mate, awesome work!!

Cheers for the comments guys. I want to have it going for next season, so that's Novemberish.

Hopefully it sounds good, only 2ltrs though so hopefully I don't have to rev the rse off it to get the benifit out of the itb's.

SR20's sound like rse, I thought the world of rallying could do with the sweet RB sound :P (SR would be better for weight distribution)

Nosmo, what ecu and sensors are you running? I'm not sure of the compression, it's on a bit of paper somewhere. Kelfords were instructed to set the head up for the highest possible compression I can run on 98 octane. MSNZ is outlawing Avgas at the mo.

ECU time...

What are your guys thoughts and experiances with Microtech LT12s ECU's?

A performance shop has recomended this to me and the price seems very fair, as long as it does what I want it to.

I need to read a Toyota TPS, aftermarket MAP sensor and do all the fuel and spark as per stanadard RB20.

Cool. Sounds like the LT12s comes with the MAP sensor going by what the supplier tells me, which will save me a few dollars. He's quoted NZ$1,650. Way cheaper that what I've been looking at previously.

That's why I'm a little bit sceptical.

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
